Drive circuit and liquid ejecting apparatus

A liquid ejecting apparatus comprising:

• an ejecting section that ejects a liquid;
• and
• a drive circuit that outputs a drive signal for driving the ejecting section, wherein
• the drive circuit includes
• a modulation circuit that modulates a base drive signal that is a base of the drive signal, and outputs a modulation signal,
• an amplification circuit that outputs a first amplified modulation signal obtained by amplifying the modulation signal,
• a reference signal generation circuit that generates a reference signal corresponding to the base drive signal,
• a level switching signal generation circuit that receives, as an input, the reference signal, and generates a level switching signal as a digital signal including a first potential and a second potential higher than the first potential,
• a level shift circuit that outputs the first amplified modulation signal as a second amplified modulation signal when the level switching signal has the first potential, and outputs, as the second amplified modulation signal, a signal obtained by shifting a potential of the first amplified modulation signal when the level switching signal has the second potential,
• a demodulation circuit that demodulates the second amplified modulation signal, and outputs the drive signal, and
• a feedback circuit that outputs a first feedback signal in response to the drive signal, and
• the level switching signal generation circuit switches a potential of the level switching signal in response to the reference signal and the first feedback signal.
